I recently upgraded from WINAMP 2.65 to 2.70 and since that time live mixes that are split into several tracks (by using exact frame splitting) refuse to be played correctly with any gapless output plugin now.
The same problem occurs with 2.71... So I got me the mp3_in.dll that is included with WINAMP 2.65 and it works fine. No more recognizable clicks / pops / gaps between the tracks with that version of mp3_in.dll. Please fix this ASAP!!!
